According to this, it is maybe.
Units of measurement aren't made up of anything. The smallest unit of measurement is the Plank unit - 10^-35m. The smallest sub atomic particle is a Neutrino, and it is made up of, a Neutrino!
No. The smallest particle of matter appears to be the electron neutrino, with a mass somewhat less than 2.2 eV. Even the electron, at 511 eV, is massive, compared to the neutrino.
The smallest particle is the muon neutrino. The subatomic particles are not measured in size; they are measured in energy. The muon neutrino has an energy of less than 0.170 MeV/c2.
An antielectron neutrino is an antileptonic elementary particle - the antiparticle of an electron neutrino.
An antimuon neutrino is an antileptonic elementary particle which is the antiparticle of a muon neutrino.
I'm not exactly sure but it's probably: electrons, neutrons, and protons.The electron is the smallest particle of the atom, in the traditional sense. However, the neutrino is far smaller than the electron, and is thus the smallest particle. You could also argue that the photon, with zero rest mass, is actually the smallest, but that's a quantum mechanics question that seems to be beyond the scope of this question.
IceCube is a particle dectector located at the South Pole and it records the massless sub-atomic particle Neutrino. IceCube is the largest Neutrino detector.

The tau neutrino has mass and is denoted with the symbol μ.
This particle is a neutron:neutron-----------proton + electron + neutrino
